The GWL/Power BMS123 Smart is a solution for monitoring and
protection of all kinds of energy storage systems, battery banks,
battery packs and other energy solutions. It was designed in view
of the growing needs for the storage of energy from solar (PV)
applications.

The GWL/Power BMS123 Smart brings you the complete system for
monitoring of the charging, discharging and balancing of the
LiFePO4/LiFeYPO4 cells with goal of reaching a complete
protection of the batteries against deep discharge and overcharge.

The GWL/Power BMS123 Smart is a fully modular system. Each
cell of the battery equipped with one small size circuit-board.
There are three types of cell circuit-boards needed for the
installation. One IN board installed on the first cell, One OUT
board installed on the last cell and a regular cell board on each
cell between the first and the last cell.

For a battery pack made of 4 cells (12V) you need only one IN,
one OUT module and two regular cell modules.

For a larger size battery packs (24V, 48V, etc) you just start
with the Complete Set (of 4 cells) and you simply purchase
additional number of the regular cell modules to install on
additional cells in between the first and the last cell. It is
easy to make a complete system for any number of cells!

For this installation you need again only 12V BMS set. Two cells in parallel are still just one cell.

Simple instillation right at the cell level

GWL/Power BMS123 Smart is really Smart: There is no
Main Controller Unit for this BMS system! Everything is
integrated at the cell modules directly. The IN and OUR cell
modules contain all the hardware components for the basic
operation of the whole BMS system. Additionally the OUT cell
module gathers all relevant data and transmits them via Bluetooth
4.0 LE (low consumption) to your iOS or Android Tablet
of Phone.

The Access to information about your battery pack was never
easier. Monitor everything remotely, including daily PV
production, daily energy consumption, or for example voltage of
all cells at the single screen. Have complete overview of your
home energy storage at you Smartphone or tablet!
